Most of the time when flying either in Europe or worldwide, the planes I travel on are nearly always full - great for the airline! On rare occasions the seat next to me may remain unoccupied - Bonus... Once flying in Upper Class from HKG - LHR the 3 of us had the whole cabin to ourselves. The question is, as a fare paying passenger, what is the emptiest the cabin has been on your flight. Don't forget to mention aircraft type and flight.
Cheers.

USAir, June 1988 SFO-LAS on a 737: Completely empty except for me and my family (Me, Mom, Dad, 2 sisters) in coach and 2 businessmen in 1st. A United HNL-SFO was on a sever mechanical delay which caused a major misconnect for all the Hawaiian's going to Vegas (this included my Grandma, and 2 aunts). Our flight was oversold but ended up going out with only 7 passengers, 4F/As and 2 pilots. I was only 5 at the time but remember this flight vividly as the F/A's showered me and my sister with an endless supply of candy and spent most of the flight just 'chillin' with my mom and baby sister (6 months old) while my dad videotaped the empty plane.

Delta 632, May 8, 2005 HNL-SFO on a 764: I was non-reving on a Buddy Pass and this plane was EMPTY. All the non-revs were cleared in to 1st which was only 1/3 full. The total load was 37 passengers out of 286 seats. I was alone in row 2 of 1st and just slept after getting my snack. GREAT service from these DL F/As on a very empty (QUIET) flight.

DL flight from SAN to PHX in 1999. 757 with 20 souls on board (including crew). Aircraft departed runway 9 and leapt off just as the wing passed over the 3rd marker, indicating only approximately 3,000 feet of runway had been used.

on an 20hundred hours something flight from LGA2CVG, i was onboard a comair crj, and there were only five pax, and the crew. was great, we took off over the Bronx and could see Time Square all lit up. sniff...i miss home.

There can't have been more than 50 people on the whole plane, maybe 30 in Y, I was supposed to be sitting on the upper deck, but they moved everyone downstairs so they didn't need to put crew and catering upstairs - I had a whole row to myself, it was great.

30-SEP-1987 - United 737-200 N9038U FLL-MIA, total pax on board 3 including me (was a continuation on a IAD-FLL-MIA trip)

30-DEC-1990 - British Midland ATP G-BMYK BHX-EMA, total pax on board 6 including five staff non-revs and only one paying pax who got off in BHX by mistake so the flight was delayed whilst she was located and reboarded (was a continuation on a LHR-BHX-EMA trip)

15 passengers on a BA 757 from EDI to LHR, last flight of the day. When airbourne informed that we could sit where we liked, I was already there and I did not see anyone move, inflight service perfect. I know its only and hour.

It might not count as it was a charter flight on behalf of a tour operator in the 1980s. I flew in a Britannia 737-204Adv from PMI to LGW via Luton. There were about 30-40 passengers from PMI to Luton. On the hop from Luton to LGW my companion and I were the only passengers left - a whole 737 to ourselves (albeit the flight was only 15 minutes or so).

I remember that I asked a cabin crew member why they were flying the plane with just us two when it surely would be cheaper to send us down to LGW by taxi. I cannot remember her exact words but basically the 737 had to go to LGW to be positioned for the next flight.
